CONTAINER TOP.

Application led April 27, 1921. Serial No. 464,833.

To all 'whom z't may concern.'

Be it known that I, Fnnunnrcn CoA'rns, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Container Tops, ofwhich the following is a speciication.

This invention relates to paper containl0 ers commonly known asZ papercans.

More particularly theinvention relates to container tops and meansof'sealing the same to the can body.

It is common in the art for heads on tops for cans of various materialswhich heads have the central portion bumped inward so that a U-s'hapedchannel is pro- -Avided around the 'head' wherein the upper edge of thecan body fits. It is also common in the art to coat the outside of thelip or top of the body, in paper cans, with an adhesive. In metalliccans the adhesive is replaced by a solder at this point. In all suchcases the inner surface of the body is uncoated and consequently acapillary crack exists between the inside of the can body and the innerleg of the U-shaped channel. As a result the can contents get into thiscrack and, in the course of storage,

` dry .out so that it frequently happensthat the contents are spoiled orare reduced in quality to such an extent as to make them` unsalable.

The principal object of the present invention is to provide a papercontainer top which is so secured to the container body as to do awaywith this capillary crack and the objections pertaining thereto.

With the above and other objects in View, as will be hereinafterapparent, the invention consists in general of an improved arrangementof paper container and top therefor.

In the accompanying drawings, 4like characters of referencel indicatelike parts in the several views, and:-

Figure 1 isl a perspective View of the container top removed from thebody.

Figure 2 is a section through such a top and the upper part of the bodybefore final sealing.

Figure 3 is a view similar to Figure 2 after final sealing.-

From the accompanying drawings it will I9 be seen that the improvedcontainer top consists' of a central disk-like portion 10 carrying aninverted U-shaped peripheral portion 11, the inner and outer legs of theU normally flaring before application as shown in Figures 1 and 2.Moreover the inner leg of the U is Lperpendicular to the body 10. Theentire inside of this channel is coated with glue as shownat 12, itbeing understood that 'the term glue includes any suitable adhesive.After coating the inside of the channel in this way the container top isplaced on the can 13. The in- A side leg of the channel will then bearagainst the inside of the body 13 at its mouth so that this inside legwill have a strat-um of glue impressed between it and the body 13. Theoutside leg is then crimped down as shown in Figure Thus there will beastratum of glue between the body 13 and the entire inside of thechannel so that there is no chance of any of the contents of the can toobtain access to the space between the container top and the body.

There has thus been4 rovided a simple and ellicient device of t e kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is:-

A paper container top consisting of a iiat central disk like portionprovided with an upstanding peripheral portion of inverted U-shape. theinner leg of-said U being perpendicular to the disk like portion and theouter leg flaring downwardly and outwardly from the inner leg, the innersur- A face of saidchannel being coated throughout with adhesive; incombination with a cylindrical container closed at one end and open atthe other, said cap being fitted in the open end of said container withthe inner leg projecting downwardly therein, the container having amouth fitting closely on said inner leg of the peripheral portion andthereby forcing excess adhesive upwardly on said inner leg. said caphaving the outer leg of said peripheral portion initially Haringoutwardly from .the container and being pressed against thecontainerfrom above downwardly thereby expelling excess adhesivedownwardly from between said outer leg and cap.

In testimony whereof I affix my signature.
